West Antarctic temperature and pressure observations begin onlyin 1957, and reliable satellite observations of Antarctic sea icedate to 1979. Comprehensive observations of glacier dynamicsin the most rapidly changing areas were initiated in the 1990s.Borehole temperature data from the WAIS, although confirmingthe recent rapid rise in temperature, do not resolve decadal-scalevariability in the past 

Assessing recent trends in high-latitude Southern Hemisphere surface climate

Antarctic climate trends observed in the satellite record are compared with a two hundred year paleoclimate record. The satellite record is found to be too short to attribute changes to anthropogenic

A 308 year record of climate variability in West Antarctica

We present a new stable isotope record from Ellsworth Land which provides a valuable 308 year record (1702–2009) of climate variability from coastal West Antarctica. Climate variability at this site

The Springtime Influence of Natural Tropical Pacific Variability on the Surface Climate of the Ross Ice Shelf, West Antarctica: Implications for Ice Shelf Thinning

During the austral spring season, significant surface warming across West Antarctica has shifted westward to the Ross Ice Shelf in recent decades in response to enhanced cyclonic circulation over the Ross Sea, which is tied to the springtime shift of the Interdecadal Pacific Oscillation to its negative phase after 1992.

Antarctica-Regional Climate and Surface Mass Budget

We review recent literature on atmospheric, surface ocean and sea-ice observations and modeling results in the Antarctic sector and relate the observed climatic trends with the potential changes in

Topographic effect creates non-climatic variations in ice-core based temperature records of the last millennium

Past temperature reconstructions from polar ice sheets are commonly based on stable water isotope records in ice-cores. However, despite major efforts in the understanding of the ice-core signal fo...

Influence of West Antarctic Ice Sheet collapse on Antarctic surface climate

Climate model simulations are used to examine the impact of a collapse of the West Antarctic Ice Sheet (WAIS) on the surface climate of Antarctica. The lowered topography following WAIS collapse

The uncertainties in Antarctic climate reconstructions due to scarcity of proxy records have restricted the understanding of mechanisms of climate change, and further hindered the improvement of

Southern Ocean surface pressure and winds during the 20th century from proxy-data assimilation

Winds and pressure over the Southern Ocean are critical to many aspects of the climate system, including ocean circulation and carbon uptake, sea ice extent, and the mass balance of Antarctica.

Onset of deglacial warming in West Antarctica driven by local orbital forcing

Results from a new, annually resolved ice-core record from West Antarctica suggest a more active role for the Southern Ocean in the onset of deglaciation than is inferred from ice cores in the East Antarctic interior, which are largely isolated from sea-ice changes.



Central West Antarctica among the most rapidly warming regions on Earth

The West Antarctic Ice Sheet is contributing to sea-level rise, but temperature trends in the region have remained uncertain. A complete temperature record for Byrd Station in central West

Antarctic temperatures over the past two centuries from ice cores

We present a reconstruction of Antarctic mean surface temperatures over the past two centuries based on water stable isotope records from high‐resolution, precisely dated ice cores. Both instrumental

Winter warming in West Antarctica caused by central tropical Pacific warming

The Pacific sector of Antarctica has experienced substantial warming in the past 30 years. Observations of global surface temperatures and atmospheric circulation data show that the warming in

A composite of water stable isotope data from high-resolution ice cores from the West Antarctic Ice Sheet shows extreme positive anomalies in the 1936–45 decade that are significant in the context of the background 20th Century warming trend.

Recent Antarctic ice mass loss from radar interferometry and regional climate modelling

Observed estimates of ice losses in Antarctica combined with regional modelling of ice accumulation in the interior suggest that East Antarctica is close to a balanced mass budget, but large losses

Little Ice Age cold interval in West Antarctica: Evidence from borehole temperature at the West Antarctic Ice Sheet (WAIS) Divide

The largest climate anomaly of the last 1000 years in the Northern Hemisphere was the Little Ice Age (LIA) from 1400–1850 C.E., but little is known about the signature of this event in the Southern

Seasonal climate information preserved in West Antarctic ice core water isotopes: relationships to temperature, large-scale circulation, and sea ice

As part of the United States’ contribution to the International Trans-Antarctic Scientific Expedition (ITASE), a network of precisely dated and highly resolved ice cores was retrieved from West

Warming of the Antarctic ice-sheet surface since the 1957 International Geophysical Year

It is shown that significant warming extends well beyond the Antarctic Peninsula to cover most of West Antarctica, an area of warming much larger than previously reported and suggested that neither can be attributed directly to increases in the strength of the westerlies.

An assessment and interpretation of the observed warming of West Antarctica in the austral spring

We synthesize variability and trends in multiple analyses of Antarctic near-surface temperature representing several independent source datasets and spatially complete reconstructions, and place

Ice core evidence for significant 100‐year regional warming on the Antarctic Peninsula

We present a new 150‐year, high‐resolution, stable isotope record (δ18O) from the Gomez ice core, drilled on the data sparse south western Antarctic Peninsula, revealing a ∼2.7°C rise in surface
